Question

interrupt solaris10 boot up, console port no more response.

Asked by: stock99

Hi,

   I tried to re-installed the solaris10 on the 2nd hand sun 280r (from ebay) , but during the cdrom boot up (via 'ok boot cdrom' command ), it hang at xxxxxxx file and arg:  

   So i power cycle the machine. After a couple of that interruption, the console port no longer give me any message but a symbol show in the code section(look like b).  If i unplug all the ram, it do get some message out of port A (complaining ram missing and power off itself).

 Please help...

ps: already unplug rsc card. The port A previously work fine till i did the stupid interrupting thing.

unplug all the power cables,  take the RSC card off the box,  and make sure all the RAM chips are fit in properly, the try to reset the NVRAM back to default:

power on the box, then type in: (need to do it fast!)

<Stop> N
to reset your NVRAM (hold the two key down for 5 or more secounds)

to see if you can get to the OBP (ok prompt).

Have a look at the hareware manual for your box in:
http://docs.sun.com/app/docs/prod/servers#hic

if you have a graphic card for Sun box, try to install the card in and plug the keyboard and mouse direct to the 280R, and connect a monitor to the graphic card, to see if you can reset the NVRAM.

i don't have graphic card.. look like my only bet is to do the stop N.
By the way, does all the RAM (i have 1GB single stick, siting all at slot 0). The ram probably not sun branded,  does it even matter?

I am not exactly sure what went wrong but below is the series of tasks i did before the OBP having issue:
1) ok  boot cdrom   ; but after up to the stage /pcixxxx/xxxx/xxxx file and arg: , it sort of hang there, the rotating cursor no longer moving.
2) I then power cycle the machine and then try to do `boot cdrom` under ok prompt, still hang. I thought it maight be because previoud data wasn't wipe before I reinsall (or i simply not patient enough!),,so i power cycle again.
3) Then I can't get anything any more on my console serial output apart from the funny character and a few dots.  So i switch into diagnose mode (using key switch)
4). The diagnositc seem to indicate sth about ram and cpu. Look like cpu has no response? I didn't copy down the full message... Then I power cycle again .
5) now even i swtich the key , can't even get back into diagnoistic mode :S
6)  Besides, i notice that now whenever i press power button key, the machine immediately shutdown. It wasn't like this before. I suppose because the OBP must hang at the cpu or memory test stage (or before those stage).
==========================

I will try to plug in a type 6 keyboard and try the key break sequence of stop+N to reset nvram.

Please have a look at the 280R manual for the details about the memory installation and memory type, I have a couple of 280R, but they are runnung, I don't have a chance to open them. (prtdiag out put from one of my box shows: 4 X 2048MB, installed in bank num 0-3)

 

by: stock99Posted on 2009-07-01 at 01:05:13ID: 24752321

When i try to boot the server today, it surprisingly give me some boot up info. But before I do stop+A it hang already. (see code snippet).


The second boot up failed as usual and blank console screen
The keyboard doesn't seem to work... I tried type 6 and smashing the stop +n and no different result. Then i realize when i press num lock key, the led on the keyboard doesn't light on.  The server only has usb port.. i dono why it doesn't like it...

IF the memory type was wrong, earlier on when i do prtdiag , i should see error message and probably wouldn't able to boot. But that wasn't the case... Still yet to go through all the document, but i feel little hope i can find there(after a quick browse of a few docs).
